Five groups are currently working to produce a vaccine for Covid 19. Four types have been used in the past for various applications. The only one that is untested is the mRNA vaccine. *If* I choose to get a COVID vaccine sometime in the future, it will be of a type which has been used successfully on multiple occasions,..such as the live attenuated virus vaccine or the inactivated virus vaccine.

But the infection rates are dropping so fast at this point, that it seems quite possible that herd immunity will be reached before I need to get any vaccine.
